STUDY OF THE EFFECT OF PHYSIOLOGICALLY ACTIVE SUBSTANCES ON THE DAMAGE OF GRAPEVINE UNDER LOW TEMPERATURES

Over the past 30 years, multiple episodes of sharp temperature fluctuations have been observed in southern Russia, which ad-versely affected the stress load of cultivat-ed plants, contributed to increased tissue damage and the risk of their complete death. In the Krasnodar Territory, regularly repeated temperature drops in winter, typi-cal for the continental climate zone, cause significant economic damage to the viticul-ture industry. Abnormal manifestations re-sult in local and systemic losses. Local con-sequences − damage to the vegetative and generative organs of grape plants, up to the complete death of plantings. Thus, the search for physiologically active substances that are potentially capable of neutralizing the effects of low-temperature stress is an important task in agriculture. The article considers the influence of various physio-logically active substances on the change in damage to the tissues of the grape vine.
